In the drawings, the broken lines defining the sidewall, inner bead, partial tread and the unclaimed sidewall depict environmental subject matter that forms no part of the claimed design. The dash-dot lines represent the peripheral boundary between the claimed tire tread and the unclaimed sidewall, and also represent the uniform repetition throughout the circumference of the tire of the unclaimed partial tread. The claimed tread pattern is understood to repeat uniformly throughout the circumference of the tire, as shown schematically in solid lines. 

CLAIM The ornamental design for a tire tread, as shown and described.
